The hydraulic pump driveshaft transmits power from the engine to the pump, setting the entire hydraulic system in motion. If you experience strong vibrations, hear metallic clunking or "ringing" from under the machine, or in an extreme case, have a sudden loss of all hydraulics, these are classic symptoms of a damaged shaft or its U-joints. Continuing to operate with a damaged shaft leads to the destruction of seals and bearings in the pump and gearbox, generating huge costs.

A precision-balanced shaft protects much more expensive components - the hydraulic pump and gearbox - from damage caused by vibrations.
Replacing the complete, factory-new shaft eliminates knocks and vibrations, restoring the machine's original operating comfort.
Using OEM quality parts is the best way to avoid unforeseen breakdowns and costly downtime.
Even if the shaft is new, U-joints should be treated as wear items. We recommend installing the shaft with new U-joints for maximum durability.
Before installing the new shaft, thoroughly check the condition of the U-joint bores in the gearbox and hydraulic pump flanges. If they are worn, they must be replaced.
Use a torque wrench to tighten the flange mounting bolts to the manufacturer's recommended specification.
Regular lubrication of the U-joints with high-quality grease, such as HYPTRON, is crucial for the lifespan of the entire driveshaft.
Answer: It is a prime suspect, along with the pump itself or the drive flange. Check if the shaft is spinning.
Question: I have strong vibrations from under the machine. Could it be the driveshaft?Answer: Yes, worn U-joints are a classic cause of drivetrain vibration.
Question: Can I replace just the U-joint instead of the whole shaft?Answer: Yes, if only the U-joint is worn and the yokes on the shaft are not damaged. If the yokes are worn, replacing the entire shaft assembly is the only correct repair.
